Peer-Reviewed Studies and Research on Chromium-6

The U.S. Department of Health and Human Services' National Toxicology Program (NTP) performed short- and long-term studies in mice that found a correlation between chromium-6 in drinking water and multiple cancers.  The results and conclusions from these studies were peer-reviewed by external experts and cited in multiple scientific journals.


In addition, scientists and environmental groups have submitted a comment letter  summarizing how industry lobbyists and the California EPA have overestimated the costs and underestimated the benefits of regulating chromium-6 in drinking water. This letter also cites multiple peer-reviewed studies.
